Ok, i about 4 months back i bought my wife a Sentra SE-R Spec V. I bought it from a small dealer that i use to work for. Before we bought it she had the ECM flashed because of the oil light coming on. About a week after we bought it the engine the dealer put in it fried the valves(bad used engine). 3 months later we got the car back, first day it throws a code for the #2 O2 sensor, he mechanic kept clearing the code. A couple weeks ago i put a muffler on the car, than it started throwing P1128 (Throttle Control Motor). The engine loses all throttle response. i took the car back and they had it for a day and supposedly "fixed it." Now today the car lost throttle response again and again and again. I have my wife take it over to the dealer who's "tech" pulled a P0605 (ECM) code. I've found on here that, that code usually means that the ECM is toasted. The dealer is trying to blame the muffler, which as someone who spent 5 years at different dealerships i know all a muffler does is muffle the sound of the exhaust. only other things i have done to the car are replace the headlights and fog lights with brighter ones and re-paint the front calipers because the paint from the guy before was peeling off. If anyone has any in sight or links to other posts that may help me, please i beg of you, this is our only car.
